Do you want to record the whole day? Or keep recording all day? Some cameras let you record on a loop and then save some loops, but the biggest problem is battery life, I use a pebble pro battery, but you can't easily connect this to a go pro with the housing.
There is one http://dashcam.co.uk/btstmembers-orig/?inf_contact_key=770e651947d7fd7664bbadec0849dfde6cde2be69264b67f8d372bd99e2b1d06 which I see has sold out, which records forever until it detects a crash or yo click a button to save a file
